Akiyoshidai

Akiyoshidai is a limestone plateau near Mine featuring grassy meadows dotted with white limestone formations rising from the ground. The landscape spreads across several kilometers and is shaped by these distinctive rocky outcrops that define the area.

The plateau began as a coral reef 300 million years ago when this region lay beneath the ocean. Over millions of years, geological processes transformed that ancient reef into the limestone formation we see today.

The yearly Yama-yaki event each February demonstrates how local people use fire to maintain the open grasslands and shape the landscape. This burning practice is deeply rooted in regional tradition and continues to define how the plateau looks today.

The site has multiple cave entrances that are easy to reach, with regular bus services connecting to nearby train stations. The best time to visit is outside the hottest summer months when conditions are more comfortable for walking and exploring.

Beneath the plateau lies an extensive cave system containing underground lakes and remarkable limestone formations accessible to visitors. The largest of these caves showcases geological features that are rarely seen and make this hidden world worth exploring.
